Specification of Letters Patent.

Application filed May 16, 1910. Serial No. 561,544.

To all whom it may concern:

Be it known that I, WILLIAM HUMPHRY PERRIN, of New Liskeard, in the Province of Ontario, Canada, have invented certain new and useful Improvements in sheaf-Shockers, of which the following is a specification.

This invention relates to improvements in sheaf shockers, and the objects of the invention are to provide an improved mechanism for upending the sheaves by means of which the sheaf may be accurately turned to a proper upended position and retained momentarily in such position until it is en gaged by the carrier of the sheaf shocking means.

Further objects are to provide an improved form of carrier and shocking means of simplified construction and adapted to securely retain and hold the sheaves until they are ready to be discharged in the form of a shock.

This and other details of the invention are more fully set forth and described in detail in the accompanying specifications and drawings.

In the drawings: Figure 1 is a perspective view of the sheaf shocker and a portion of the binder mechanism. Fig. 2 is a perspective view of the cam controlling one of the discharge arms. Fig. 3 is a perspective view of the carrier controlling mechanism. Fig. 1 is a perspective view of the supporting member adapted to support the butt of the sheaf during upending. Fig. 5 is a perspective view of one of the arms of the carrier. Fig. 6 is a perspective view of the supporting member adapted to support the upper end of the sheaf during upending. Fig. 7 is a perspective View of one of the upending discharge arms. Fig. 8 is a perspective view of the other upending discharge arm.

In the drawings, like characters of reference indicate corresponding parts in each figure.

It may be mentioned that the general construction of the sheaf shocker is similar to that which I have described in my earlier United States Patent No. 806,283, granted Dec. 5/05. Certain features are also described in my United States application Serial No. 179,840, filed Feb. 24/09.

Referring to the drawings, A represents the binder deck and B represents in a general way the knotting mechanism.

According to the present invention, the sheaves are engaged one by one by rigid arms having hook members adapted to engage the cord on each sheaf, said hook members being adapted to be simultaneously turned downwardly to discharge the sheaves in the form of a shock.

C represents the shocking mechanism as a whole, located stubbleward of the binder deck. This mechanism includes a rotatable carrier D formed with rigid radially extending arms 10, each of which arms is formed with an inner section 11 extending substantially horizontally and an outer section 12 extending substantially vertically. The arms in the particular embodiment illustrated are supported from a rotatable frame 13 suitably mounted on a vertical shaft (not shown) which is geared to a horizontal shaft journaled in a sleeve 14: and driven from a port-ion of the binder mechanism in a manner more particularly de scribed in my earlier patent and application.

At the extremity of each radial arm, a pivoted hook member 15 is provided adapted to be actuated by suitable means to grip the cord on the sheaf and disengage the same at the proper moment. The means for operating these arms comprise an axially movable frame 16 mounted on the same shaft as the frame 13 and being formed with similar radial arms 17 which have their extremities connected to a point on the hook members a short distance removed from the pivoting points thereof, whereby, as the members 17 are raised and lowered, the hook members will be turned upwardly and downwardly. The frame 16 tends to move to lowermost position by gravity in which position it will be separated from the frame 13, but this movement is ordinarily prevented by means of a lever 18 which is centrally fulcrumed to a projection 19 on the frame 13 and has the inner end connected to the frame 16 while the outer end carries a pin 20 adapted to engage a cam 21 on the sleeve 14, which cam has at one point a depression 22 therein, as described in my earlier application, by means of which the pin at one point is freed and may move upwardly, at which point the frame 16 will move downwardly by gravity carrying all the arms 17 downwardly and tilting the hook members 15 to discharged position, when the sheaves carried thereby will drop in the form of a shock. The inner sides of the sheaves are adapted to be supported on the carrying member by a core member E which is conoidal in form and carried by the frame 16.

The upending mechanism for the sheaves comprises two discharge arms adapted to tilt the head of the sheaf upwardly, a retaining member for the butt of the sheaf and supporting members for the butt and head of the sheaf said retaining and supporting members being operated by the sheaf itself. Two discharge arms F and G are carried by the shaft 21 of the knotting mechanism and are adapted to collapse at a given point to permit the sheaf to pass them. This is accomplished by forming each arm with an outer pivoted section 22 which pivoted section is during the greater part of its rotation retained in alinement with the inner section 23 by means of a cam 24 or 24* which is engaged by the inner end 25 of the pivoted section, the pivoted section of the arm F having a roller 26 thereon to engage the cam while that on the arm G has only a cylindrical projection 27.

The cam 24 which cooperates with the arm F is formed near one extremity with an abruptly and outwardly inclined portion 28 adapted to impart a kick or sudden tilting movement to the section 22 just prior to its collapse, whereby, the sheaf will be thrown smartly to vertical position. The cam 2 1 cooperating with the arm G is not formed' with such a projection, as this arm engages the sheaves farther down from the head and it is not necessary that it should be thrown upwardly as quickly.

The butt of the sheaf is retained from swinging upwardly by a rigid retaining arm 29 curved to engage the upper part of the butt of the sheaf. The lower part of the butt of the sheaf is adapted to be engaged by a movable supporting member 30 which is adapted to be operated by the sheaf itself during its movement. This arm is formed with an inner portion 31 which is pivoted to a bracket 32 which extends at a slight angle to the binder deck and also with an outer upwardly inclined portion 33. This inclined portion is adapted to be engaged by the butt as it comes down the binder deck and will thus restrain the outward movement of the butt. As the sheaf is turned however, to a vertical position, it will engage the side of the portion 33, causing the arm to tilt in the direction indicated by the arrow in Fig. 1 and thus permit the sheaf to pass the arm as the sheaf is carried away by the carrier.

To support the headof the sheaf during the turning movement, a supporting member 35 is provided hinged to the binder deck and normally held in raised position. The

means illustrated for holding it in raised position comprise a spring 86 wound about the shaft 37 which supports the member, said shaft being j ournaled in suitable brackets 38 carried by the binder deck.

The relative position of the carrier D to the discharge mechanism of the binder is such that each arm will be successively turned in such posit-ion that at the moment the sheaf is upended the hook member will come into position just below the cord on the sheaf and the sheaf will thus be engaged by the hook member. Each arm then passes on the grainward side of the supporting member 35, the supporting member yielding outwardly during the upending of the sheaf and returning to the inner position indicated in Fig. l, as soon as the sheaf is caught on the hook, whereby, the sheaf and hook may pass onward to the stubbleward side of the supporting member. The mechanism is so adjusted that the sheaves will fit closely to the core E and will be overlapped thereon so that when discharged they may form an effective shock.

The operation of the machine may be summarized briefly as follows: The sheaf moving down the binder deck is retained momentarily by the arm 29 engaging its butt at the same time as the discharge arms F and G engage the upper part of the sheaf and upend the same as already explained.

The supporting members 30 and 35 are actuated by the sheaf itself as hereinbefore explained. The moment the sheaf assumes a substantially vertical posit-ion it is met by one of the arms on the carrier D and the cord slips onto the hook member thereon and the sheaf is carried away. Finally when all the arms have been filled, the hook members are simultaneously discharged, dropping the sheaves in the form of a shock.

As many changes could be made in the above construction and many apparently widely diiferent embodiments of my invention, within the scope of the claims, con-' structed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.
